The KSZ series boiler is a cast iron oil-fired low pressure steam boiler designed for use in closed heating systems. This boiler must be vented by natural draft into a lined masonry or metal chimney, or Type L vent. An adequate supply of air for combustion, ventilation and dilution of flue gases must be available in the boiler room. This boiler has connections for use with an indirect domestic water heater. The KSZ series boilers are not designed for use in process or other “open” steam systems.
